糖尿病大鼠骨代谢的变化

目的研究糖尿病早期骨代谢改变。方法测定６周实验性糖尿病（ＳＴＺ－ＤＭ）大鼠空腹血糖、ＨｂＡ１ｃ、胰岛素、钙离子浓度、骨钙素、降钙素、ＰＴＨ和维生素Ｄ３。收集２４ｈ尿，测定白蛋白、肌酐、吡啶酚。结果糖尿病大鼠与正常对照组相比，血清钙浓度显著升高［（１３５．８５±１１．２８）对（１１７．２１±６．５２）ｍｇ／Ｌ，Ｐ＜０．０１］，骨钙素水平升高［（０．０７±０．０４）对（０．０５±０．０１）ｎｇ／ｍｌ，Ｐ＜０．０５］，维生素Ｄ３水平显著降低［（７．６３±１．８８）对（１１．５５±４．１１）ｎｇ／ｍｌ，Ｐ＜０．０５］，尿吡啶酚／肌酐显著降低［（４．７９±０．７５）对（７５．８４±６０．６７）ｎｍｏｌ／ｍｍｏｌ，Ｐ＜０．０１］；而血清降钙素和甲状旁腺素水平改变无统计学意义。结论糖尿病状态下存在骨代谢异常，主要表现为维生素Ｄ３降低、骨钙素升高及尿吡啶酚水平降低。糖尿病性骨质疏松可能与维生素Ｄ３水平降低及由于胰岛素缺乏所致的骨胶原合成障碍有关     

2型糖尿病颈动脉内膜中层病变及相关危险因素分析

目的：分析2型糖尿病患者颈动脉内膜中层厚度（CIMT）及其相关危险因素。方法：采用彩色多普勒超声仪测量115例2型糖尿病患者CIMT,并根据CIMT值将全部患者分为A组和B组,其中,A组患者62例,CIMT值≥1．0mm,B组患者53例,CIMT值〈1．0mm。比较两组血糖、血压和血脂等代谢指标,并对与2型糖尿病CIMT增厚的相关危险因素进行评估。结果：A组患者的年龄、糖尿病病程、高血压病程、低密度脂蛋白胆固醇（LDL—C）、体重指数（BMI）明显高于B组,差异均有统计学意义（均P〈0．05）,而两组三酰甘油、总胆固醇、高密度脂蛋白胆固醇、糖化血红蛋白、空腹血糖、餐后2小时血糖水平差异无统计学意义（P〉0．05）。经Logistic回归分析显示,年龄、糖尿病病程、BMI、LDL—C水平是2型糖尿病患者CIMT增厚的独立相关危险因素（OR=1．093、1．088、1．038、1．732,均P〈0．01）。结论：2型糖尿病患者CIMT增厚受多种因素影响。尤其与年龄、肥胖、糖尿病病程和LDL—C水平密切相关。     

Omentin-1 attenuates adipose tissue inflammation via restoration of TXNIP/NLRP3 signaling in high-fat diet-induced obese mice

Omentin-1 is an adipokine expressed by the adipose tissue and is reduced in obesity. This study was designed to calculate the protective efficiency and mechanism of omentin-1 against inflammation of the adipose tissue in obese mice. A transgenic mouse model with omentin-1 protein overexpression was established by crossing omentin-1 transgenic mice with Fabp4-Cre mice. Obesity was induced in the mice by feeding them a high-fat diet for 10 weeks. Fabp4-Cre-mediated overexpression of omentin-1 significantly increased serum omentin-1 level, serum anti-inflammatory factor levels, and expression of M2-specific mRNAs; inhibited body weight and adipose tissue weight gain; improved glucose tolerance, insulin tolerance, and insulin sensitivity; decreased serum levels of insulin and proinflammatory factors, adipocyte size, and expression of M1-specific mRNAs; suppressed macrophage infiltration; downregulated expression of proinflammatory factors; upregulated expression of anti-inflammatory factors; and inhibited thioredoxin-interacting protein (TXNIP)/NOD-like receptor 3 (NLRP3) signaling in the adipose tissue of obese mice. An NLRP3 inhibitor (20 mg/kg MCC950) exhibited the same effects as overexpression of omentin-1. Pretreatment with omentin-1 inhibited lipopolysaccharide-induced inflammation via TXNIP/NLRP3 signaling in RAW 264.7 macrophages. These findings suggest that omentin-1 suppresses adipose tissue inflammation in obese mice, at least partly, via inhibiting the TXNIP/NLRP3 signaling pathway.

急性缺血性脑卒中患者早期活动方案的行动研究

目的探讨基于行动研究法的急性缺血性脑卒中患者早期活动方案的实践效果。方法采用行动研究法,对急性缺血性脑卒中患者早期活动及其态度进行问题识别,再按照计划-行动-观察-反思的螺旋循环过程,基于循证构建急性缺血性脑卒中患者早期活动方案与流程、制定家属参与早期活动方案,并经过2轮行动方案的实践,观察早期活动实践规范的实施效果。结果第2轮早期活动方案实施后患者早期活动开始时间、活动频率、活动强度、神经功能缺损程度、日常生活活动能力、不良预后、住院时间与第1轮比较,差异有统计学意义(P0.05,P0.01)。结论规范急性缺血性脑卒中患者早期活动方案,可显著缩短早期活动的开始时间,提高患者活动频率与活动强度,从而促进患者神经功能恢复,改善患者预后。     

童年期创伤经历与抑郁症状:新兵积极心理品质的中介和调节效应

目的 探讨新兵积极心理品质在童年期创伤经历与抑郁症状之间的中介和调节效应.方法 采用随机整群抽样法抽取南方某部1 925名16～24岁的男性新兵,运用童年期创伤经历问卷(CTQ-SF)、抑郁自评量表(SDS)和新兵积极心理品质评估问卷(PMCS-R)进行测评.结果 童年期创伤经历问卷的情感虐待为(6.11±1.69)分,躯体虐待为(5.49±1.32)分,性虐待为(5.61±1.45)分,情感忽视为(9.15±3.66)分,躯体忽视为(9.57±2.93)分;抑郁严重指数(0.45±0.11);积极心理品质总均分(3.80±0.64)分.童年期创伤经历、抑郁症状和积极心理品质得分两两显著相关(均P＜0.05);情感忽视、躯体忽视和情感虐待能有效预测抑郁症状,可共同解释其总变异的28.6％ (F=256.72,P＜0.05);积极心理品质在情感忽视和抑郁症状、躯体忽视和抑郁症状、情感虐待和抑郁症状的关系中均有部分中介效应(中介效应分别为0.19,0.15和0.09),但只在情感忽视和抑郁症状间调节效应显著(F=24.73,P＜0.05).结论 童年期创伤经历不仅直接作用于新兵的抑郁症状,也能通过积极心理品质间接作用;同时,新兵的积极心理品质可以改变童年期创伤经历对抑郁症状的影响.     

Management of high-grade squamous intraepithelial lesion patients with positive margin after LEEP conization: A retrospective study

To explore the optimal way to manage patients with high-grade squamous intraepithelial lesion (HSIL) and positive margin by identifying the risk factors for its recurrence and residue.A retrospective study was conducted on 267 cases of a pathologically confirmed HSIL with positive margin following conization by loop electrosurgical excisional procedure (LEEP) between January 2010 and December 2015. One hundred two cases were selected for regular follow-up every 6 months, and 165 cases were selected for a second surgery (repeat cervical conization or hysterectomy) within 3 months of initial LEEP. We analyzed the association between recurrent or residual diseases and these factors: age, menopausal status, ThinPrep cytologic test (TCT) results, high-risk human papillomavirus (HR-HPV) infection, pathological grades of the margin, number of involved margins, and glandular involvement.The recurrence rate among 102 cases who underwent follow-up was 17.6% (18/102). The factors: atypical squamous cells of undetermined significance cannot exclude HSIL (ASC-H) or higher lesions in the pre-LEEP TCT (P = .038), persistent HR-HPV infection at the 6th month post-LEEP (P = .03), HSIL-positive margin (P = .003), and multifocal-involved margin (P = .002) were significantly associated with recurrent disease, while age, menopause, and pre-LEEP HR-HPV infection were not associated with recurrent disease (P > .05). The residual rate among 165 patients who underwent a second surgery was 45.5% (75/165), of which 15 cases were residual cervical cancer. The factors: menopause (P = .02), ≥ASC-H in pre-LEEP TCT (P = .04), pre-LEEP HR-HPV infection (P = .04), ≥HSIL-positive margin (P < .001), and multifocal-involved margin (P < .001) significantly increased the risk of residual disease. No correlation existed between residual disease and age or glandular involvement (P > .05).For patients with a positive margin after LEEP, regular follow-up or second surgery should be selected according to fertility requirement and pathological characteristics of the positive margin, as well as TCT and HR-HPV infection condition.     

Efficacy and feasibility of deep brain stimulation for patients with depression: A protocol for systematic review and meta-analysis

Background:Previous meta-analyses have examined the clinical efficacy and acceptability of deep brain stimulation (DBS) compared with sham therapy or paired active therapy. However, the absence of head-to-head clinical trials with some treatment comparisons creates uncertainty for decision makers. Thus, to provide new evidence-based medical evidence for clinical treatment, we undertook a meta-analysis to assess the efficacy and safety of DBS in patients with depression based on high-quality randomized controlled studies.Methods:The protocol was written following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) statement guidelines. PubMed/Medline and EMBASE will be searched before May 2021 for all studies, using various combinations of the following free text and key terms: deep brain stimulation; depression; random. No language restrictions will be applied. The method of data extraction will follow the approach outlined by the Cochrane Handbook for Systematic Reviews of Interventions. Review Manager software 5.3 is used for the meta-analysis. The quality of randomized trials will be assessed by Cochrane risk of bias tool for randomized controlled trials.Results:The results of our review will be reported strictly following the PRISMA criteria and the review will add to the existing literature by showing compelling evidence and improved guidance in clinic settings.OSF registration number:10.17605/OSF.IO/Q5B3S.
